“…3 There is no particular reason for us to consider the above ansatz except for its simplicity. 4 As we have seen in the previous section, for the two parameter model there are indeed solutions which are not of the above form. With arbitrary parameters it is in extremely difficult to construct the general solution without taking any specific ansatz.…”

In this paper we study spherically symmetric single-centered attractors in N = 2 supergravity in four dimensions. The attractor points are obtained by extremising the effective black hole potential in the moduli space. Both supersymmetric as well as non-supersymmetric attractors exist in mutually exclusive domains of the charge lattice. We construct axion free supersymmetric as well as non-supersymmetric multiple attractors in a simple two parameter model. We further obtain explicit examples of two distinct nonsupersymmetric attractors in type IIA string theory compactified on K3 × T 2 carrying D0 − D4 − D6 charges. We compute the entropy of these attractors and analyse their stability in detail.

Abstract:We investigate the thermodynamic and hydrodynamic properties of 4-dimensional gauge theories with finite electric charge density in the presence of a constant magnetic field. Their gravity duals are planar magnetically and electrically charged AdS black holes in theories that contain a gauge Chern-Simons term. We present a careful analysis of the near horizon geometry of these black branes at finite and zero temperature for the case of a scalar field non-minimally coupled to the electromagnetic field. With the knowledge of the near horizon data, we obtain analytic expressions for the shear viscosity coefficient and entropy density, and also study the effect of a generic set of four derivative interactions on their ratio. We also comment on the attractor flows of the extremal solutions.

“…Due to the attractor mechanism [7][8][9][10][11], the Bekenstein-Hawking [12,13] entropy of an EBH is a function only of the electromagnetic charges; in most of the N = 2 models with symmetric scalar manifolds, as well as in N > 3-extended theories, 1 the entropy is given by (π times) the square root of the absolute value of the U-duality quartic invariant I 4 [14,15] (also see, e.g., [16,17] for introductory reviews and lists of references).…”

Peccei–Quinn Transformations and Black Holes: Orbit Transmutations and Entanglement Generation

Abstract:In a recent paper (Mod. Phys. Lett. A 2015, 30, 1550104), the black-hole/qubit correspondence (BHQC) was exploited to define "black hole quantum circuits" allowing for a change of the supersymmetry-preserving features of electromagnetic charge configurations supporting the black hole solution. This resulted in switching from one U-duality orbit to another, or equivalently, from an element of the corresponding Freudenthal triple system with a definite rank to another one. On the supergravity side of BHQC, such quantum gates are related to particular symplectic transformations acting on the black hole charges; namely, such transformations cannot belong to the U-duality group, otherwise switching among orbits would be impossible. In this paper, we consider a particular class of such symplectic transformations, namely the ones belonging to the so-called Peccei-Quinn symplectic group, introduced some time ago within the study of very special Kähler geometries of the vector multiplets' scalar manifolds in N = 2 supergravity in D = 4 spacetime dimensions.
